Dams, Levees, Canals & Temporary Water Retaining Structures
MEA’s design support and evaluation of water retaining systems, such as dams, containment impoundments, levees, cofferdams, and canals require meticulous attention and monitoring. Oftentimes, subsurface investigation, and detailed seepage and slope stability analyses are necessary to properly design the feature. To avoid failure potential within a water-retaining embankment or structure, field inspections, groundwater monitoring, and porewater pressure measurements can be taken during long-standing operation of the structure.
